In this episode, Stanford hosts and Dr. Syed Mohiuddin, Chief AI Transformation Officer at UnitedHealth Group, discuss how AI is fundamentally transforming both clinical practice and individual lives as of 2025. With the rate of consumers who trust AI as much as their doctor surging in just one year, the center of healthcare is shifting beyond simple "disease treatment" toward everyday "prevention and health management." In particular, they strongly predict that a bottom-up transformation -- driven by consumers and clinicians voluntarily choosing and demanding AI -- rather than top-down government-led change, will drive cost reduction and innovation in healthcare.

1. 2025: A Changed Daily Life -- Is AI Replacing Doctors?

The conversation opens with a fascinating personal anecdote. Dr. Syed, himself a physician, confesses that the number of calls he makes to fellow doctors when medical questions arise in his daily life has noticeably decreased.

In the past, when a family member or acquaintance fell ill, he would have immediately called a specialist friend. But now, asking AI first has become routine. AI filters the initial information, and he only consults a human expert for truly complex and important issues. This shows that even medical professionals are using AI as a "first gateway for medical consultation."

"The overall volume of questions has increased five- to tenfold. I can get immediate answers to minor curiosities. Meanwhile, the number of times I directly contact a specialist has dropped by 50%. You could say productivity has increased ten- to twentyfold."

This shift isn't limited to professionals. A Bain survey cited in the episode reveals striking numbers. Between 2024 and 2025, the percentage of consumers who said they "feel comfortable accepting AI as my doctor" surged from 11% to roughly 30% in just one year.

"These numbers are really powerful. That's a 2.5x increase in just one year. ... Patients are now choosing AI. At this rate, the number could reach 50% next year. In a healthcare system that usually moves very slowly, this pace of change is truly extraordinary."

2. From "Sick Care" to True "Health Care"

The panelists see AI as the key to solving healthcare's chronic problems of supply shortages and access barriers. Patients must wait weeks to see a doctor, and when they finally do, the visit lasts only 15 minutes. So who manages the remaining 364 days?

Dr. Syed explains that the future of healthcare will be completely transformed through personalized LLMs (large language models). Once every patient has their own AI agent, they can receive real-time management of diet, exercise, and metabolic status even outside the hospital. This frees physicians to focus on high-complexity cases that truly require expert judgment rather than routine management.

"We are moving toward a world where AI agents help individuals with more than just 'sick care.' It's a world where someone can say, 'Yes, I have diabetes, but I have dietary advice tailored to my metabolic status right at my fingertips.'"

"AI extends my scope of practice. It handles administrative tasks and low-risk questions, allowing me to focus more on what made me love medicine in the first place -- solving difficult cases and providing the best possible care for patients."

In other words, AI is not replacing doctors but rather serving as a reliable partner that helps doctors work more efficiently as the "quarterback of care."

3. Voluntary Innovation Without Policy Change

It's easy to assume that changes in healthcare require shifts in government policy or reimbursement structures (fee schedules). But host Justin points out that the current adoption of AI is happening through natural demand (pull) without any policy changes.

According to a Menlo Ventures report, a significant portion of healthcare AI investment currently focuses on administrative automation (scribing, coding, billing, etc.). But the panelists say this is only the tip of the iceberg.

Currently, hospitals and insurers are adopting AI for administrative tasks to reduce costs, but they predict that clinical AI will grow explosively within the next 3-5 years. This will go beyond simply assisting with paperwork to play a core role in analyzing patient data, delivering precision medicine, and improving clinical outcomes.

"There are so many categories that don't show up in today's reports. I think the clinical AI space will become enormous within 3 to 5 years. Beyond just improving provider productivity, it will connect more data and better data to realize scalable precision medicine."

Dr. Syed specifically emphasizes that the goal for massive organizations like UnitedHealth Group is to be "deflationary -- lowering costs while benefiting more people." The positive outlook is that efficiency gains through AI will ultimately contribute to reducing healthcare costs.

4. In Five Years, Healthcare Will Be Completely Different

Near the end of the discussion, Dr. Syed delivers a very strong "hot take." He warns that within the next five years, the healthcare industry will look completely different from today, and companies that cling to old ways will lose their footing.

At the center of this transformation is the patient (citizen). If past healthcare innovations (such as the adoption of electronic medical records) were imposed top-down by the government, this AI revolution is a bottom-up innovation where consumers seek better experiences and make their own choices.

"This industry will be completely different in five years. ... If incumbent companies insist on doing things the way they've historically done them, their roles will diminish significantly. Because the most important person in this ecosystem is the patient -- the citizen. They will choose, and they will have options to choose from."

"If you want to drive change, you have to show users that what you're offering is 'meaningfully better.' You can't just throw money at it or push regulation. ... I feel this change is different from the past because it's coming from the bottom up."

Closing

This episode demonstrated that healthcare AI is evolving beyond merely assisting doctors' workflows to becoming a partner that proactively manages patients' lives.

All panelists agreed that "this time is truly different." Because patients and doctors are directly experiencing AI's convenience and usefulness, and demanding it forcefully. In 2025, we are witnessing a historic moment where healthcare is fundamentally restructuring -- from provider-centric to consumer-centric, and from treatment-focused to prevention-focused.
